ABSTRACT

A superhydrophobic nanocoating generates a superficial thin film on a textile substrate, which results in a self-cleaning surface that repels water contaminants. Lotus leaves exhibit self-cleaning properties and remain clean in contaminated water. Despite significant research and advancements in superhydrophobic structures, the fundamental principles of the design to create self-cleaning surfaces are largely similar. Commercially several self-cleaning products based on the lotus effect are available, and some more products are in the development phase. The accomplished self-cleaning properties with new functionalities must be consolidated for the next generation of superhydrophobic coatings, for example, optical transparency, in a coating that is produced using reasonable materials and is adequately durable for regular use. The fabric surface can be made superhydrophobic and oleophobic by nanosphere formation on the surface of the treated fabric and, therefore, the fabric can be endowed with self-cleaning properties, as reported for the lotus effect.
